fix(prefs): bump schema sentinel for keyboard_type field (PR #21)

Browse Source 
keyboard_type was inserted into the append-only NodePrefs layout without
bumping SCHEMA_SENTINEL, leaving it at 0xC0DE0019 — the same value plain
main already uses without this field. A device already on that schema
would silently misalign every field read after alarm_min once updated
to a build containing this change. Bump to 0xC0DE001A and fix the
migration comment's stale version label (it said 0xC0DE0018, which was
already taken by the MAP home-page migration).
